DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Briefly press the button; the DTC indicator
lamps in the instrument cluster come on.
Deactivating DTC again
Press the button again; the DTC indicator
lamps in the instrument cluster go out.
Deactivating DTC and DSC together
Press the button and hold it down for at least
3 seconds; the DSC indicator lamps in the instrument cluster light up. Stabilizing and
drive-output promoting actions are no longer
executed.
To increase vehicle stability, activate DSC again
as soon as possible.
Reactivating DSC
Briefly press the button; the indicator lamps in
the instrument cluster go out.
To control
If the indicator lamp flashes:
DSC or DTC controls the drive forces
and brake forces.
If the indicator lamps are on:
Both DTC and DSC have been deac-
tivated with the DTC button.
If the indicator lamps are on:
DTC has been activated with the DTC
button.
Malfunction in driving stability control
systems
These warning lamps come on:
The driving stability control systems
and the Flat Tire Monitor have failed.
Proceed cautiously and drive defen-
sively, avoiding full brake applica-
tions. Have the system checked as
soon as possible.

Technology for driving comfort and safety
80 If the warning lamps for DSC come
on. DSC including DTC and DBC is
malfunctioning.
The stabilizing action and brake-
servo boost are no longer available. The vehicle
remains operational. Have the system checked
as soon as possible.
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the handbrake for this.
1.Hold the car in place by pressing the brake
pedal.
2.Release the brake pedal and drive off with-
out delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake pedal is released. Depending on vehicle
load, the car may roll backwards a little during
this time span. Drive off without delay after
releasing the brake pedal. Otherwise, the drive-
off assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards.<
Malfunction
The warning lamps for the brake sys-
tem light up in yellow. The drive-off
assistant has failed. The car will not
be held in place after the brake pedal
is released. Have the system checked as soon
as possible.

dian models.
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.If a tire loses pressure, its rolling radius
changes, and this in turn alters the speed of
rotation. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>If snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<
iDrive concept, refer to page16.

Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Run-Flat Tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, moreover, no spare wheel is
available. Your BMW center will be glad to
advise you.
For safety reasons, BMW recommends
that damaged Run-Flat Tires be replaced
rather than repaired.<
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view. Specialist tire dealers and your BMW center
can supply these labels.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the sidewall
of the tire.
Snow chains*
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information. Attach snow chains in pairs
and only to the rear wheels. Observe the manu-
facturer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
You are not permitted to mount snow chains to
tires of the following sizes:
>255/40 R 17
>255/35 R 18
>255/30 R 19
Do not initialize the Flat Tire Monitor if
snow chains are mounted, as the instru-
ment might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to switch on DTC temporarily, refer to
page79.<
